First, raw_cmd_ioctl calls raw_cmd_copyin. This function kmallocs space for a floppy_raw_cmd structure and stores the resulting allocation in the "rcmd" pointer argument. It then attempts to copy_from_user the structure from userspace. If this fails, an early EFAULT return is taken. The problem is that even if the early return is taken, the pointer to the non-/partially-initialized floppy_raw_cmd structure has already been returned via the "rcmd" pointer. Back out in raw_cmd_ioctl, it attempts to r
